Abstract

A high-efficiency water tank for public toilet is composed of water tank body, water filling pipe, siphon drainage pipe and water-holding turning over hopper, and features that the water tank body is divided by partition plate into water storage cylinder at its lower part and water storage cavity at its upper part, the siphon drainage pipe with siphon mouth in water storage cylinder is conic, and the diameter of siphon mouth is 1.5-2.5 times that of water outlet. Therefore, compared with the prior water tank for the toilet, the utility model has the advantages of convenience, sanitation, large water saving amount, regular flushing, jet effect during flushing and good flushing effect. The utility model can also realize manual or automatic control according to the requirement. And can be used for flushing toilets of trains, ships, families and the like.

Description

The efficient water tank in public lavatory

The utility model relates to the efficient water tank in a kind of public lavatory, is to the improvement of existing public lavatory with flusher.

In known technology, the flusher of height (low) cisten mechanism is adopted in the lavatory more with flusher.This flusher fault rate is higher, is prone to the running water phenomenon, and water consumption is very big.People at joint, water aspect problem done a large amount of improvements to the lavatory flushing device, invented the patent No. and be 87203068 the high level cistern flushing variable waterworks and the patent No. and be 89209718 water-saving lavatory flushing device.These two kinds of flushers have all changed the water supply modes of flusher in the past, all have certain water-saving result.But above-mentioned flusher all need manually discharge water.If use in the public lavatory, some people is afraid of to be reluctant communicate illness to discharge water, and this just is difficult to reach the cleaning effect of anticipation, directly influences the sanitary condition in public lavatory.Therefore, the inventor has invented a kind of public lavatory high-efficiency multi-function water economizer, and the patent No. is 90206170.4, this patent has the timing automatic function that discharges water, water-saving result is also very remarkable, but not good enough because of its structure design, fails to reach the ideal designs requirement in aspect results of use such as scouring forces.

The purpose of this utility model provides the efficient water tank in a kind of public lavatory, make its timing automaticly discharge water, aspects such as water saving and flushing ability reach the ideal designs requirement, to solve the deficiencies in the prior art.

The utility model is to be that design is improved with the high-efficiency multi-function water economizer in 90206170.4 public lavatory at the patent No..It comprises water tank, water injection pipe, siphon drainage pipe and is filled with water the upset bucket.Its water injection pipe be positioned at water tank top and with the upset bucket centering that is filled with water.Be characterized in that it is that water storage box, top are for installing the cavity of upset bucket that the water tank inner-use clapboard is divided into the bottom.The siphon drainage pipe that siphon port is positioned at the storage cylinder of water bottom is the conical pipe structure, and the 1.5--2.5 that its siphon port diameter is its outfall diameter doubly can reach the jet effect during flushing.

Upset bucket of the present utility model is fixed in the upper cavity of water tank and can overturns around the shaft by rotating shaft, be provided with lean forward the location fulcrum and the location fulcrum that resets of upset bucket on the dividing plate in water tank, upset bucket rear portion is provided with to reset uses Weight plate, adopt this structure after upset bucket fills with water, just can realize tumbling forward automatically, automatically reset by its rear portion Weight plate then.

For structure of the present utility model is more become rationally, the bottom in the water tank is with dividing plate it to be made the storage cylinder of water of side band siphon barrel structure, and the water holding volume V1 at its siphon tube place and the water holding volume V2 of upset bucket should satisfy V2 〉=1.5V1.Like this, result of use of the present utility model is better.

The utility model is to improve design on the basis of No. 90206170.4 patents.Therefore, structure of the present utility model more becomes simply, rationally.The utility model is used for developing result the best of large-scale public watering privy, can regularly wash, and convenient and healthy, water-saving amount is big, has jet effect during flushing, and developing result is good.The utility model can also be used for the flushing in each layer of high-rise building lavatory, only needs at top this water tank of installation, just can control the timing in each layer lavatory flushing now in fact, promptly saves material, and is convenient and healthy again.The utility model also can be used for the automatic flushing in lavatories such as train, steamer, family, and water-saving result is remarkable.Particularly be low to moderate 0.1kg/cm at hydraulic pressure ²In time, still can normally use, and never lost efficacy.

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is the A-A cut-away view of Fig. 1.

Among the figure, water tank 1 can be made with galvanized sheet or corrosion resistant plate, profile can be made into oblate cylindricality, upper and lower two cavitys will be separated into dividing plate 2 in the water tank 1, upset bucket 3 is fixed in the upper plenum of water tank and 4 upsets around the shaft by rotating shaft 4, following cavity is to be with the storage cylinder of water 11 of siphon tube 10 for making its flexible overturning, and bearing is installed additional in 4 two ends bearings in rotating shaft.Rotating shaft 4 simultaneously is located at upset bucket 3 bottoms, and its axis should satisfy L1: L2=4 apart from the relation of upset bucket front end L1 and rear portion L2: 3.Being provided with on the dividing plate 2 in water tank leans forward decides fulcrum 5 and resets location fulcrum 6.Base plate and dividing plate 2 as the location fulcrum 5 that leans forward join, and promptly having surrounded the retaining volume is the siphon tube 10 of V2, the location fulcrum when tumbling forward as upset bucket 3 again; Base plate as the anchor point 6 that resets is the location fulcrum that sets back after upset bucket 3 is tumbled.Be equipped with the sponge silencing pad at lean forward the location fulcrum 5 and fulcrum 6 places, location that reset, to alleviate that upset bucket 3 is tumbled and when resetting and the hard collision of supporting-point.Automatically tumble forward during upset bucket 3 filled with water, it resets and is to install Weight plate 7 realizations additional by upset bucket 3 rear portions.Siphon drainage pipe 9 is the conical pipe structure, and its elbow part is positioned at siphon tube 10 places on storage cylinder of water 11 tops and dividing plate 2 is concordant with the elbow lower wall of siphon drainage pipe for good.The water sucking mouth diameter of siphon drainage pipe 9 is chosen as 90mm, and its outfall diameter is chosen as 40mm, so just can reach jet.As the outfall end of siphon drainage pipe 9 is designed to 90 ° bend pipe, developing result is better.
